How do Unicom users untie their mobile phones?

Is the serial number bound between the contract machine and the contract card. Do you want to untie it now?

If it is within the contract period, it cannot be unbound. During the contract period, the machine card needs to be used together. Otherwise, the complimentary phone bill cannot be returned. After the contract expires, it will be automatically unbound, and the machine and card will be used separately.

If the card is reissued within the contract period, the serial number of the mobile phone card needs to be rebound in the business hall after the card is reissued. Lost or broken mobile phone: the mobile phone is broken, so you need to go to the mobile phone repair point to prove it. If the mobile phone is lost, it is necessary to provide proof materials such as a report receipt issued by the public security organ to prove that the mobile phone is lost. Then take the proof materials to the business hall. After verification, the advance payment will continue to be returned to the account. After that, how to implement the number agreement within the agreement period needs to consult the local business office.
